I just configured my athlon k7@500, AMD motherboard, UDMA/33 ide disk,
voodoo3 3000 graphic board, and I want just to share a
really-rapid-and-out-of-the box lmbench result. First row is the k7,
the second one the office PII Deschutes@333. Kernel is plain 2.2.13 in
the first case, 2.2.13+PCspeaker in the second one. 686-compiled.
cd results && make summary percent 2>/dev/null | more
make[1]: Entering directory `/home/romano/tmp/lmbench-2alpha11/results'

The mtrr question is... I tried to activate the write-combining on the
Voodoo3 framebuffer, and the PC (the k7 one, I mean) locked solid. I
will try some 14pre this weekend... is it a known special effect of
athlon?
